Long-Range Outcomes

There are a number of anticipated long-range outcomes for the SBAR project including:

  1. Improved biomass quantity and quality for guayule and guar through genetic improvement and traditional breeding, including a measured rate of apomixes specific for each USDA NPGS guayule accession.
  2. Development and distribution of irrigation tools to help regional growers increase production while reducing water use.
  3. Improved understanding of microbial community populations to support optimal production for guayule and guar that will lead to a 25% increased yield.
  4. Transportation systems analysis and optimization model developed for each feedstock, and data integrated into sustainability models for co-production of fuel, rubber, and guar gum.
  5. Risk assessment completed for grower, fuel producer, and byproduct producer needs, and a guidance document and tool-kit developed for stakeholders.
  6. An increase in guayule and guar farming in the Southwestern U.S.
  7. A greater understanding of U.S. biofuel production by K-12 students and graduate students, and youth exposed to degrees and jobs in new and exciting agricultural and energy-related fields.


“Through SBAR’s work, we are able to increase the economic sustainability of two crop plants, for which we already have primary products, by developing and evaluating other uses for additional compounds found in the plant, and the materials left after harvesting and processing.”
~ Dr. Dennis T. Ray, SBAR Co-Principle Investigator, University of Arizona


“Developing a low water-use crop like guayule will produce per acre revenues that are competitive with alfalfa and cotton in the arid Southwest.”
